You have made an easy and common mistake. The GStreamer SDK is not
associated with the GStreamer project, despite the name. I have never used
the GStreamer SDK. I really don't know why it was created. You should look
here -> http://gstreamer.freedesktop.org/ for the latest documentation,
source and binaries. And yes, GStreamer 1.0 is *NOT* compatible with
GStreamer SDK. The SDK code is very old.
